Grand Prix SE 3800

  • Automatic transmission
  • 74,000 miles

2008 Grand Prix 75K, Highway speed stumble only when AC is on, more consistent on bumpy stretches of interstate 80. I am suspecting a wire to wire short or pinch but I don't have a clue where to start looking...yet! Suggestions anyone?
